This year, for the first time ever, the TED Prize went not to an individual, but to an idea on which our planet's future depends: the City 2.0.

For one day only, the TEDx platform will harness the power of people across the globe to encourage them to host a TEDx event themed "City 2.0" event at their favorite local spots, featuring the brightest local minds and biggest hearts. In unison, we'll share the stories of our beloved homes: where are the bright spots? The creative adaptations? The transformative responses to injustice? Who is asking the most pressing questions? Pioneering the most complex solutions? Speakers can focus on themes including culture, transportation, education, sanitation, recreation - all elements whose presence will dictate the success of our future cities.
